Microchip SAMA7G5 devices supports runtime changes of CPU frequency.
This is doable by changing CPUPLL frequency along with MCK0 frequency.
Along with this CPU's regulator must be changed to accommodate new
frequencies.

Did you try to reuse cpufreq-dt driver? It already handles most of
this stuff, the only thing you need to do is to make sure
clk_set_rate() for a CPU needs to handle all the clk stuff behind the
scene.

We haven't been accepting new implementations of the drivers which can
work just fine with cpufreq-dt, please try to adapt to it.

Thanks.
